シンポジウム S07 -- 3月7日 9:30-12:30 A会場
Overabundant sika deer populations eliminated most of palatable plants and shift to alternative food such as unpalatable plants and even fallen leaves in recent decades. The questions arise why high density deer populations could be sustained under severe resource limitation. The aim of the symposium is to search the process and mechanism through comparing several sika deer populations on population dynamics, vegetation changes and life history traits living in various environments. We invite Dr. Steev Côté as leading researcher of this topic and Dr. Seiji Kondo as a commentator in the field of feeding ecology of livestock, and by combining with our own talks, we would like to discuss the linkage between overabundant deer, ecosystems and their life-history.
[S07-1] Impact of population irruption of sika deer on vegetation and feedback effects on their life history on Nakanoshima Island, Hokkaido
[S07-2] A long term study on the population change of sika deer, Cervus nippon, and the vegetation dynamics on Kinkazan Island, northern Japan
[S07-3] Effects of food quality and availability on food habits, body size and pregnancy rate of sika deer: comparison of the two contrasting habitats, Nikko and Ashio areas
[S07-4] Population dynamics of sika deer, habitat changes and life history traits of sika deer on Boso Peninsula, central Japan
[S07-5] Impacts of overabundant white-tailed deer on ecosystems and feedback effects on their life-history
